20120315904 | OPTIMIZED USER RE-DISTRIBUTION OVER S-CSCF ENTITIES - Embodiments of the present invention provide a network entity of an IMS network, in which a registered user is being served by an assigned Serving-Call Session Control Function, S-CSCF. The network entity includes a memory storing data that includes an identity of at least one better-matching S-CSCF in the IMS network having capabilities better suited for serving the registered user than the assigned S-CSCF. The network entity is configured to obtain an indication of the availability of the better-matching S-CSCF, and when the better-matching S-CSCF entity is available to initiate a transfer so that the registered user is served by the better-matching S-CSCF. The network entity may be the assigned S-CSCF, or may be an I-CSCF. Embodiments of the present invention provide a method of transferring a registered user to a better-matching S-CSCF. | 12-13-2012 |
20110207451 | METHOD AND ARRANGEMENT IN A TELECOMMUNICATION SYSTEM - Methods and devices for coding a slot in a cellular radio system are described. The coding allows for increased robustness and can be designed to be backwards compatible with transmission for e.g. GSM, GPRS, EGPRS and EGPRS2. | 08-25-2011 |
20110203775 | System in a Network Node for Regulating Temperature of Electronic Equipment - A system in a radio network node for regulating temperature of electronic equipment comprises the electronic equipment and a heat exchanger unit ( | 08-25-2011 |
20100232293 | Uplink congestion detection and control between nodes in a radio access network - Congestion in a radio access network (RAN) associated with transporting uplink information originating from one or more mobile terminals is detected. That detected RAN congestion is reduced using any suitable technique (several examples are described) and may be implemented in one or more nodes in the RAN. One advantageous (but non-limiting) application is to a RAN that supports high speed uplink packet access (HSUPA) and/or one or more enhanced uplink dedicated channels (E-DCHs). | 09-16-2010 |
20100216483 | SELECTION OF TRANSMIT MODE DURING A RANDOM ACCESS PROCEDURE - The invention discloses a method ( | 08-26-2010 |
20100177633 | Priority Flow Handling in Stateless Domains - A method of managing quality of service in an IP network is provided. The method comprises identifying, at an egress edge node of the network, that congestion is present in one or more routers within the network. Data flows for termination to remove the congestion are selected. At least one flow termination notification is sent from the egress edge node to an ingress edge node of the network, the at least one flow termination notification identifying the selected data flows. Low priority flows from the selected data flows are terminated at the ingress edge node immediately. High priority flows are terminated only if congestion is still present after a predetermined delay period. The delay may be applied in the ingress edge node or the egress edge node. The invention also provides a method for admitting low priority flows into the network only if the network has resources available for a number of high priority flows above a dynamically determined threshold. | 07-15-2010 |
20090257533 | SYSTEM AND METHOD OF RECEIVING AND PROCESSING MULTICOMMUNICATION SIGNALS - A receiver receives and front-end processes a plurality of component carrier signals, each carrier spaced apart in frequency. The digitized, baseband component carrier signals are inspected to determine estimates of timing offsets between the carriers. A control unit selects a first component carrier signal having data scheduled to the receiver. If data is scheduled to the receiver on other component carrier signals, the control unit generates timing and frequency offset adjustment control signals to time- and frequency-align each other component carrier signal having relevant data, to the first component carrier signal. All the relevant component carrier signals are then combined, and a single OFDM symbol, spanning all the relevant component carriers, is presented to an FFT for symbol detection. | 10-15-2009 |

20090125628 | Service subscription associated with real time composition of services - Real-time service composition is provided by a Session Initiation Protocol (SIP) transport binding for Simple Object Access Protocol (SOAP) messages. A SOAPAction header and SOAP envelope can be included in a SIP message to identify a requested service. The SIP message recipient can parse out the SOAP envelope and forward same to a corresponding Web Service. An intermediary node, including a SIP Proxy, can evaluate incoming SIP/SOAP messages and provide requested services to which they have access. Service discovery and subscription are facilitated by adding Universal Description, Discovery and Integration (UDDI) services requests and responses. | 05-14-2009 |
20080207196 | Evaluation of Random Access Preamble Codes - The present invention relates to methods and arrangements for gathering statistics relating to random access operation in a cell of a cellular radio communication network and supervising such random access operation. Statistics are gathered ( | 08-28-2008 |
